This chapter approaches climate change both as an atmospheric-chemical and geophysical phenomenon and as a discursive interface for heated debates in politics, society, and science. My remarks here serve to highlight the complexity of climate change as the defining dispositif of our time. I focus my considerations on the task and challenge of documentary films to represent climate change and make it imaginable. I then refer in particular to the temporal dimensions of climate change. On the one hand, the scarcity of time contains the normative level of the call for rapid counteraction and, on the other hand, the long-term dimension of the concept of climate eludes direct and immediate perceptibility. Based on the time-critical dimension, I first provide an overview of the current climate research consensus and the political and activist setting. Regarding the long-term dimension of climate change, I then take up ontological and socio-philosophical debates on the positionality of humans, science, and society within transdisciplinary climate change knowledge production. I round this off with an excursion on the controversy of the Anthropocene.
